Lol could someone explain to me the answer and how they got the answer I'm very confused about it
Bingel [31]

I'm assuming the deck is the shaded area.

To find the area of the deck, find the area of the large circle and subtract the area of the small circle from it:

A of large circle: R = (4.2/2) + 1.7 = 3.8; area: 3.8^2 * pi is about 45.3.

A of small circle: r = 4.2/2 = 2.1; area: 2.1^2 * pi is about 13.8

Now, subtract:

45.3 - 13.8 = 31.5 meters squared

Please give the actual reason clearly because everything i tried won’t give me the 2 needed marks
777dan777 [17]

Answer:

Step-by-step explanation:

Angle BAC = Angle ACD = 50 degrees, because they are alternate angles.

Angle ACB = 180 - (50 + 80) = 50 degrees, because angles in a triangle sum up to 180 degrees.

Since Angle BAC = Angle BCA, triangle ABC is isosceles.
